To all whom. 'it may concern.'

Be it known that I, Zo'riK E. CHERNESKY, citizen of Russia, residing atMilwaukee, in the county of Milwaukee and State of Wisconsin. haveinvented certain new and useful Improvements in Portable Fans, of whichthe following is a specification.

This invention relates to fans such as are used for cooling purposes inrooms of any kind, the invention having for an object to provide a noveltype of fan, driven by iuid pressure instead of the commonly usedelectric motor.

Other specific objects of the invention relate to the adjustment of thespeed of the.

fan, and the angle of its axis.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawin s, and to the appended claims in whlch t evarious novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a perspective view of my improved fan showingits application to a house -faucet.

Fig. 2 is a side elevation, with vertical section, of the fan.

Fig. 3 is a rear view. Q

Fig. 4 is a horizontal section on the line 4-4 of Fig. 2.

As here shown the motor of -my improved fan comprises a circular casing10 having feet 11. In this casing is mounted a vane wheel of anyapproved construction, the casing having inlet and outlet openings 13and parts in 14 for the motive fluid. The top of this.

casing is in the form of a removable plate 15 on which is fixed abearing frame 16.

The wheel 12 is fixed on a vertical shaft 17- extending upward through astuiiing box 18 in the plate 15 and Supported at its upper end in theframe 16a.

Pivotally attached as at 2() to the frame 16 is a bracket 21 in which isjournaled a horizontal stub shaft 22 having the fan 23 fixed at one endand a bevel pinion 24 fixed to its other end, a spur pinion 25 beingfixed to said shaft intermediate its ends. The

bevel pinion 24 is adapted to mesh with one face of a double faced bevelgear 26 feathered on shaft 17 and movable into and out of engagementwith pinion 24 bymeans of a U-leverv27 fulcrumed as at 28 to the frame16 and connected by links 29 to a collar 30 swiveled on the hub of gear26. The lever with the pinion 25, and a bevel gear 37, the

relative Sizes of the parts being such that the bevel pinion 37 will bespaced some distance from the bevel gear 26 when the latter is held outof engagement with the pinion 24. The pinion 37 is adapted to be broughtinto engagement With the lower face of gear 26 by swinging the bracket21 on its pivot 20. The speed of the fan 231s thus increased, while itsaxis is changed so that it directs the current of air downward. rlhebracket 21 is held in adjusted positions by meansof a collar 40, looseon a pin 41 projecting from the free end of the bracket, and adapted toengage of a pair of sockets 42 formed in a part 16 of the frame 16, thispart being slotted as vat 44 to receive the pin 41. A spring45'surrounding the pin 41 urges the collar 40 toward the socket 42.

In' use, the inlet 13 of casing 10 may be connected by a pipe 47 to anordinary faucet such as 48 on a sink 49, an exhaust pipe 50 Having thusdescribed my invention what I claim as new and desire to protectbyLetters Patent of the United States is as follows:

1. In combination, a motor, a frame, a bracket hinged to said frame, afan mounted on said bracket, a pair of spaced bevel pinions havingdifferent ratio drive connections with said fan, said bracket beingadapted to be swung to different positions to vary with the angle of thefan and bring either of said bevel pinions into operative relation tothe motor.

2. In combination, a rotary Huid motor, a vertical shaft on which saidmotor is ixed, a frame, a bracket hinged to said frame', a

' a bevel pinion and a spur pinion all fixed on said stub shaft, asecond stub shaft, said Spur gear meshing with said spur pinion, Saidbevel pinionS lying in a commonplane and spaced from one another, adouble faced bevel gear feathered on said vertical shaft and projectingbetween said bevel pinions, means for moving said bevel gear along saidvertical shaft to bring it into or out of mesh With said first mentionedbevel pinion, and n means for holding said bracket in position with saidsecond bevel pinion in or out ofv \ab1e thereon and adapted to en,g.;age in either mesh vvith said beve'lgear.

3. In a combination, a rotary Huid motor, a vertical shaft 'on whichsaid motor is fixed,

' a frame, a bracket hinged to said frame, a

stub shaft journaled in said bracket, a fan, a bevel pinion and a spurplnion all fixed on said. stub shaft', a second stub shaft jourt naledinsaid bracket, a spur gear and a bevel pinion on said second stub shaft,said spur Gear meshing with said spur pinion, said bevel pinlons lyingin a common spaced from one another, a dou le vfaced bevel gearffathered on said vertical shaft and projecting between' said bevelpinions, means for moving said bevel gear along-said vertical shaft tobringit into'or out of mesh with said lfront mentloned bevel pinion, and

`means for holding said bracket in position with saidsecondbevel pinioninV or out of mesh with said bevel gear, said means including a pin onsaid bracket, a collar slidof a pair of sockets in said frame, and aspring urging said collar toward said brackets. 1- i In testimonylwhereof I 'have aiiixed my signature, v I' e zoTIK oHERNEs-KY.
